ApplicationSeptember 14, 1933, Serial No. 689,477 solai-ms. (cl. 1464106) Patronsof lroadside sandvs'icl'l` stands and similar eating places have createda demand for sandwiches which consist of a roll or biscuit hav-` ing anopening bored therein from one end and a sausage or other ediblecommodity inserted inr` the opening. The present invention'has for itsobject the provision of a. simple, inexpensive and eliicient mechanismwhereby the desired opening or socket may be readily andrapidy formed inthe biscuit or roll withoutexcessive waste and without marring theappearance of the roll.. It is also an object of the invention toprovidemeans whereby the bored roll will 'be delivered from the holderautomatically; The invention is illustrated in the accompanying drawingand will be hereinafter fully described, the novel 1 features beingdened inthe appended claims.

In the drawing, f l

Figure l is a plan view of yan apparatus embodying the presentinvention,

Figure 2 is a longitudinal section on the line` 2-2 of Figure 1,

Figure 3 is a transverse section on the line 3 3 of Figure 1.

Figure 4 is a longitudinal section of a roll inA which an opening hasbeen'made.

In carrying out the present invention, there at one side of the opening3, is a small electric motor 6 which may be of any known form and isillustrated in a conventional manner only. An auger 7 is secured uponthe end of the motor shaft and is equipped at its end with a reamer orbit 8 which is removably secured to the auger so that bits of differentsizes may be interchangeably used, as desired, and a sharp bit may besubstituted easily for a bit which has become too dull for furthersuccessful use. Upon reference to the drawing, it will be noted that theauger is located directly over the opening 3 in the base and, therefore,crumbs whichmay be turned froml the roll in the boring operation will becaused to drop through the opening and collect in the drawer. Securedupon the base, in alinement with the motor and the auger, is a guideplate 9 having an opening 10 therein which registers with the opening 3in the base, as shown, said plate 9 being secured upon the basebycountersunk fastening screws 11 which pass through spacingblocks l2wherebythe plate will be disposed `in spaced relation to the base. f Abox or holder 13 is slidably mounted upon the plate 9 and is adapted tobe pushed to and from the auger when a roll, indicated at 14, is to havean opening formed therein. The bottom and 'end of the holderarepreferably formed of wood and the bottom is provided with a centralnotch 15 to accommodate ,the ngers of the operator placing a roll in theholder. The sides of the holder are .preferably formed of sheet metaland extend below the bottom, the lower edges of the side. walls beingturned inwardly to define anges 16 which engage under the edges of theplate 9, as clearly shown in Figure 3, and thereby retain the holderupon the plate and also guide it in its movements. r

As clearly shownin Figure 3, the side walls o the holder are insections, the lower section being rigidly secured-to the edges of' theholder bottom and the upper sections being connected to the lowersections by spring hinges 18. On the inner'sides of the sidewalls,immediately adjacent the lower edges thereof, arek inwardly projectin'glugs 19 which engage a false bottom 20 in the holder. This false bottomis hinged, as shown at 21, to the closed end ofthe holder, and a spring22 bears against its under side and tends constantly to swing itupwardly, as indicated by dotted lines in Fig. 2. On the underside ofthe false bottom, near the free end thereof, is secured a resilientlatch 22 which projects downwardly through an opening 23 in the truebottom and engages a lug or catch 24 to hold the false bottom inV itslowered position, recesses 25 being provided in the end walls of theyopening 3 to accommodate the latch. The false bottom has a notch 26 inits free end corresponding to the notch 15 in the true bottom, and anotch 2'7 in the guide plate accommodates the latch.

The operation of the device will now be readily understood. The roll isplaced within the holder, which has an open top and end, with one end ofthe roll abutting the closed rear end of the holder, as clearly shown inFigure 2. The holder, with the roll therein, is then pushed toward theauger which is rotated by the motor in an obvious manner, and the end ofthe augerk will engage the end of the roll at the center thereof so thatan opening will be formed in the roll longitudinally thereof, as shownat 17 in Figure 4.

`The engagement of the sides of the holder with the guiding andsupporting plate 9 maintains the Cil roll in proper alinement with theauger, and the spacer blocks are so arranged that they will notinterfere with the movement of the flanges 16. The roll, however, cannotbe pushed beyond the side of the motor or the motor casing and,consequently, the opening formed by the auger will not extend entirelythrough the roll but will leave one end thereof closed, also as shown inFigure 4. All the crumbs Which are drawn from the roll by the auger willdrop at once into the drawer 2 and, when the drawer has been lled, itmay be removed and suitable disposition made of the crumbs. The crumbswill be clean and are generally uniform so that they need not be thrownaway but may be utilized in cooking wherever bread crumbs are nowemployed.. The device is very simple and compact, and will make make theopenings in the rolls rapidly and of uniform character and of properdiameter to accommodate a sausage or other commodity which may bedesired. v

By interchangeably using bits 8 of various sizes, the diameter of theopenings in the rolls may be varied so as to accommodate commodities ofdifferent thicknesses, and the exterior of the roll will be left intactand without any marring of its appearance.

The roll, in the holder, rests on the false bottom between the sideswhich are held in upright position by the pressure exerted upon the lugs19 through the false bottom.l When the holder recedes from the auger,the false bottom remains in the lowered position until the latch isbrought against the end wall of the recess 25, whereupon the impactreleases the latch and the spring 22 immediately swings the false bottomupwardly, the upper side sections turning outwardly under the influenceof the springs at the hinges 18. It will be noted that lugs 19 areplaced close to the hinge 21 so that the outward movement of the sideswill be limited although they will free the roll which may be easilyremoved. When another roll is placed in the holder, reverse movement ofthe parts will occur so that the roll will be firmly held until after ithas been bored and released as described.

Having thus described the invention, I claim:

1. An apparatus for the purpose set forth comprising a support having anopening therein, a

power driven auger mounted on the support, a receptacle upon the supportbelow the opening therein, a guide plate secured upon the support inspaced relation thereto and having an opening below the auger andregistering with the opening in the support, a bread holder slidablymounted on the plate and movable toward and away from the auger, saidbread holder including a false bottom having one end thereof pivotallyconnected with the holder, and means for elevating the free end of thefalse bottom to partially eject the bread from the holder afterretraction from the auger.

2. An apparatus for the purpose set forth comprising a boring tool, anda roll-holder movable to and from said tool and including a falsebottom, swinging sides, means whereby the sides will be held raised whenthe false bottom is lowered, a latch for holding the false bottom inlowered position, and means for raising the false bottom when the latchis released.

3. An apparatus for the purpose set forth comprising a support having anopening therein, a boring tool mounted on the support at one side of theopening, a holder slidably mounted on the support to move to and fromthe boring tool, the holder having an upwardly swinging false bottom andhinged sides, yieldable means tending constantly to swing the sidesoutwardly, yieldable means tending constantly to swing the false bottomupwardly, lugs on the lsides engaging under the false bottom whereby thesides will be heid raised, and a latch on the false bottom engaging thetrue bottom of the holder to hold the false bottom lowered, said klatchdepending into the opening in the support to be released by impact uponthe end wall of theopening upon withdrawal of the holder from the boringtool.

4. An apparatus for the purpose set forth comprising a boring tool, abread holder movable toward and away from the tool, said bread holderincluding a movable bottom having that end thereof remote from theboring tool pivotally connected with the holder, and means for elevatingthe free end of the bottom to partially eject the bread from the holderafter retraction from the boring tool.
